Formerly known as Cymric, the Manx cat is one of the oldest cat breeds, originating back to the Isle of Man. They are well-known for either having bobtails or no tails at all. Typically playful, this intelligent breed has been compared to dogs, as they love to run, play, and follow their owners. The downside to this cuddly breed is that they are wary of strangers and will become extremely aggressive if they feel that their owners are in danger. In addition, although normally playful, as mentioned earlier, their cheerfulness usually doesn’t extend to children and/or dogs. In fact, the Manx cat may act aloof and distant.
